[Q] Got Stuck on Download Mode. Need Help 4.3

Hello there,
I've previously used Odin to install several versions on several phones, so at leas I know some very basics, like, using Odin and what not.
Here's my problem. I rooted my 4.3, it gave me some trouble, and the main reason I wanted it rooted was to get backups for my apps. Turns out I can back up my data with carbon "rooted-unrooted" so I decided to ditch the root since it was giving me some hassle with the security update thing and titanium was not working properly. "had to do some other stuff and I was kind of tired.
Turns out I tried to install my other official firmware I had "4.1". Sadly, upon using Odin with it, it now says that I'm trying to install an unsupported version and won't proceed... I'm stuck in here because I cannot restart by pressing up+power because it gives me an error and says I need to restart in download mode.
I was wondering if installing a fresh copy of 4.3 would fix this. Yet I've been unable to find any actual official files... yeah... I know this sounds pathetic, but... I've been herer for an hour + and have not found either a solution or the original 4.3 file or whichever file I would need for this.
Decided to turn unto this community which has helped me a lot in the past to solve all my previous issues.
So... How do I install a fresh 4.3 or how do I get out of this mess? My cell phone doesn't turn on, it just tells me the following:
Firmware Upgrade Encountered an issue. Please select recovery mode in Kies & try again.
I had 4.3 installed with all the security crap on it, so when I go to download mode and install 4.1, it says that the verison is unsopported...
Thank you all in advance.

Download Mr Robinson's 4.3 rooted ROM from here.
Flash it via ODIN and you should be good to go.
Your phone is already on 4.3 bootloader and it is not letting you downgrade to any version below it.

Help Plz - Boot loop brick, Tab 3 7.0

Hello all,
I've got a Tab 3 7.0 T210R stuck on the Samsung logo with pulsing blue background. I've read through several Samsung boot loop help threads as well as the general Loop noob helper but haven't found a fix yet.
For my stuck T210R, What I've done & can do:
Was rooted with a "patched" stock UK ROM from last March [sorry, don't recall which]
Was running fine until after I tried to install from Play the TWRP Manager, I obviously did something bad! like select wrong device maybe
I can get into Philz, TWRP, & use Odin
I don't have a recovery back up [i really don't care about restoring back to anything - just want it to work, clean slate, ya know]
Tried a couple of latest ROM's through Philz and a stock ROM XAC-T210RUEAMK1-20131122134958.zip though ODIN. They seemed to be successful but I still can't get past Samsung logo
I've tried these ROMS that seem to load but ixna on successful boot afterwards:
ODIN: KIES_HOME_T210RUEAMK1_T210RXACAMK1_1304745_REV00_user_low_ship.tar.md5
Philz: Stock.rooted.deodexed.T210R.zip
Philz: TAB3-T210-HASSAN-ROM-V1.0-kitkat-4.4.2-Aroma-Mods-all Languages.zip
Philz: cm-10.1-20131209(1)-UNOFFICIAL-lt02wifiue.mine.zip
What's killing me is that loading new or stock ROM's SEEM to work - no errors or anything obviously indicative that I'll still be boot looping as soon as I restart. I'm quite desperate and thinking I'm truly bricked.
I haven't yet tried using ADB but if I can use ODIN and TWRP or Philz, will ADB do anything better than what I've already done? I haven't tried anything with the kernel as I can't really understand what to do there. I read and read and read the kernel threads but with my experience its really not as straight forward as rooting or flashing a ROM or software, and I could conceivably screw up worse! I'm mildly experienced at following guides to have rooted and ROM loaded a 1st gen Kindle Fire, Samsung SII skyrocket, S4, Tab 2 7.0, Tab 3 7.0.

No replies or interest? Please help
I'm I in the wrong forum? Did I offend someone? Could really use some input, please.
Any one seen this before? If you've any experience LOSING this battle, please speak up and I'll know to just resign to now owning a pretty white Samsung brick.

if i could find the "thanks" button I'd use it.
I'm traveling now but definitely try your solution. By "redo" I presume you mean load a ROM. When I wipe I also presume I'll still have custom recovery? I should still be able to ODIN, too, if needed?
thanks again

Yes exactly recovery will not go away once you have formatted the partitions you can now flash a new customed ROM or reflash original FW using Odin..Cheers

Hey buddy wanted to know if you ever found a solution for your issue? I am in the same bind you were in. Can you help guide me. I tried installing the same files you did and to no avail. I bought a Tab 3 T210R from eBay that was stuck in boot loop, I am assuming that it isn't rooted as when I would I went into download mode, it said the firmware was official.

"https://forums.oneplus.net/threads/guide-how-to-unroot-your-oneplus-3-and-go-back-completely-to-stock.456232/"

When you have TWRP you have to install full zip, not simply the eval OTA zip

Flash the stock recovery.
Get stock recovery from downloads.oneplus.net

I cant seem to flash the stock recovery. The device is not visible in adb devices or fastboot devices. im facing the same issue.

If you are using TWRP 3.0.4-0 - try a hard boot...hold down the power button for 20s...wait 20s, power it back on.

easy solution. Boot into fastboot
download this tool.
https://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
if newest version isnt working, download an older version with older twrp
than unzip the tool and run the .bat file and install twrp.
Thats it

There are many posts on Nougat not working with official TWRP (based on 6.0 build). Try booting into stock recovery. performing a system settings reset, then booting into fastboot and run the adb command, <fastboot boot TWRP-3.0.2-1.28.img>. From there you can do virtually anything you need to do. I recommend at least using a modified version of TWRP (such as 1.28). This has been posted many times before, please try and do a search for the answers first, it will help tremendously. Thanks

i had the same problem on my rooted OP3 when i used TWRP 3.0.2-1 , it worked to flash the full 4.0.1 rom but failed for everything else, flashing latest verion of twrp fixed it for me

Got the same problem (unrooted phone + device state locked, cannot access recover, but can access fastboot) with an added "benefit", USB debugging mode was off before it all went crashing and burning.
How to access my phone via PC? (all the guides I've found assume I had USB debugging mode on before the phone got soft-bricked, but as a normal phone user who never installed anything custom, I've never figured it is A MUST BE ON function).
Or simpler question - what tool to use to turn on the USB debugging mode? (if that is at all possible?)

Noted that you solved your issue, but this post is about the new version of TWRP. Version 3.0.3 is available on twrp.me and it works with Nougat.

Unable to boot phone once TWRP installed?

Hey guys,
So I've been trying for days to get a custom Ron installed on N975F.
Right now I'm on completely reflashed stock Rom. With stock recovery et al. No root.
I am able to flash Magisk with Odin. No trouble. And my phone continues as usual without issue.
However, once I install TWRP, no matter where or how I install it, once I restart my phone it will boot past the warnings without issue, then go to the screen that just says "SAMSUNG" and the phone will never actually boot up.
I can still boot into TWRP recovery without issue, but system itself will never boot, it will just sit on the "SAMSUNG" screen forever.
In fact, it seems like as long as TWRP is installed to recovery, my system will never boot with any Rom. It can be fixed by reinstalling stock recovery, or by reflashing stock in it's entirety (which I have now done before I try again).
Has anyone got any ideas why this might be occurring or how I can address it? I saw some threads about 'rollback protection' but it seems like that is for people who are not even able to boot into TWRP, or get stuck on the first "Samsung Note 10+", screen rather than the system booting "SAMSUNG" screen.

i am guessing try ADB commands see this link! https://www.koskila.net/how-to-use-twrp-to-flash-an-android-device-that-refuses-to-boot-to-twrp/

Many N975 users have reported this issue and I have forwarded concerned to ian as well. What I believe is formatting on latest (last few) twrp causing issue.
If you have N975/N976 then, visit xda My rom thread - Download area - you will find a folder "for stock rom & bootlooped device" download instructions and follow it, I have wrote guide with or without flashing my rom
Edit :
here is direct link, you will find all required file

This guide is stop solution to root/root with twrp/fix Samsung roll back bootloop everything. And yes you don't needs to patch anything yourself, all files available are ready to use

Hi Dr Ketan,
Thanks for the response.
I actually solved the issue simply by using the version of TWRP and following the install instructions on your basic "How to Root and Install TWRP" for Note 10+ guide.
So I think this is a problem relating to Ian's latest TWRP. TWRP linked from your thread
is working fine (but leads to issue with Camera in GSI/Lineage OS ROMs).
I will have a look at your special guide relating to Samsung logo/rollback stuff and see if it will allow me to install latest TWRP from Ian and bypass these issues! Thank you.

Yes, As I said issue is related to newer TWRP only. If you use old TWRP, camera will not work. My above link guide is for latest base and you can get latest TWRP only (Included package are having latest available TWRP & Kernel)

S21 Exynos booting into a flashing/looping TWRP

Greetings,
New to XDA and looking for some feedback on issues run into when attempting to root a Samsung S21 G991B/DS Exynos. I unlocked the boot loader and attempted to flash twrp (twrp-3.5.0_10-1_afaneh92-R-o1s-1.tar) and Multidisabler (vbmeta_disabled_R.tar) in Odin and it passed and booted the phone into a looping or flashing TWPR screen. The phone is not allowing me power down the phone and I cannot get back into Odin, recovery, or download mode. I used the following instructions and got to step 9:
Root Samsung Galaxy S21 SM-G991B/N and Install TWRP Recovery 3.5.0
Easy tutorial to Root Samsung Galaxy S21 SM-G991B, SM-G991BN on Android 11 One UI 3.1. For rooting, you have to firstly flash TWRP Recovery 3.5.0.

Any feedback would be greatly appreciated. I would also be willing to consult and pay with anyone who can help me remedy this issue and get the phone rooted.
Thanks,
Todd
